Southern California 1931: Amongst the burgeoning urban sprawl built atop bulldozed orange groves and the bitter realization that you can’t eat the sunshine, recent emigré James M. Cain found a kernel of truth and his voice, which would eventually distill through his novels, ”The Postman Always Rings Twice,” “Mildred Pierce” and “Double Indemnity” and subsequent film adaptations into the unique American genre: Film Noir.

How did this East Coat sophisticate go from managing editor of “The New Yorker” to populist novelist accused of writing dirty books? The tour explores Cain’s L.A. from Hollywood to Glendale and along old Route 66, and includes illuminating visits to Forest Lawn Memorial Park (a Glendale institution and site of the funeral of Mildred Pierce’s “other” daughter, Ray), the Glendale Train Station where the “Double Indemnity” murder plot played out, and the punch line to a Billy Wilder joke so subtle, it’s taken 63 years for anyone to get. The tour will also cover the artisans who transformed Cain’s tales into film, including Billy Wilder, Raymond Chandler, Joan Crawford and Lana Turner, each an important contributor to the Film Noir canon.
